A robust reversible data hiding scheme for H.264 without distortion drift

This paper proposes a robust readable reversible data hiding scheme in H.264/AVC. We encode the embedded data using BCH syndrome code (BCH) before data hiding to improve robustness, then we embed the encoded data into the quantized discrete cosine transform (DCT) coefficients of the 4 x 4 blocks of I frames which meet the directions of intra-frame prediction, and the directions of intra-frame prediction are utilized to avert the distortion drift. The experimental results show that this new robust reversible data hiding algorithm can get more robustness, effectively avert intra-frame distortion drift and get good visual quality.
